ABOUT COLOUR continued
You can check that your document is in CMYK process colour in one
of three ways:
1
By printing ‘separations’ on your desktop printer – see the Help fi le
that came with your application for more details. If anything other
than cyan, magenta, yellow and black separations print, then you’ve
unwanted colours that you need to convert. This is also a good way of
checking knock-out/overprinting settings.
2
Or create a PDF fi le and use Adobe Acrobat Professional’s Output
Preview tool to check the separations.
3
Or create a PDF fi le as a Separated PDF
Some RGB and Spot colours do not have a direct CMYK equivalent – the
technical term for this is “out of gamut”. If you have chosen a colour
that is out of gamut, your software will choose the closest equivalent
CMYK colour, which may be different from the colour you intended.
This is something that everyone has to put up with, so for best results,
we strongly recommend that you choose colours from our colour
charts. These have been produced on our presses and will give a more
predictable indication of the colour.
